It covers a variety of imaging approaches including diffuse optical imaging, laser speckle imaging, photoacoustic imaging and optical coherence tomography.

Speckle imaging describes a range of high-resolution astronomical imaging techniques based on the analysis of large numbers of short exposures that freeze the variation of atmospheric turbulence. They can be divided into the shift-and-add method and the speckle interferometry methods. These techniques can dramatically increase the resolution of ground-based telescopes, but are limited to bright targets.

Combined laser speckle imaging and fluorescent intravital microscopy for monitoring acute vascular permeability reaction. Optical clearing agents (OCAs) and many chemicals are widely used in functional diagnosis of skin tissues.

Each laser speckle device prototype allows the choice of up to three different laser wavelengths in the range of 400 nm to 800 nm in total. Tools for processing laser speckle images from a camera License. GPL-3.0 License Releases No releases published. Packages 0. No packages published .

Laser speckle imaging of GB34, ST36, EX-LE2, and BL40 and the nonacupoint site. (a) Laser speckle imaging of BL40 (1). BL40 is located at the back of the knee, on the popliteal crease, in a depression midway between the tendons of biceps femoris and semitendinosus.

High degree of coherence, on the other hand, accompanies unexpected background speckles across overall image so Laser Doppler, speckle and related techniques for blood perfusion mapping and imaging R37 Figure 1. A typical laser speckle pattern. Figure 2.

Visualizing fluid flows has many applications in various fields of science and engineering. The imaging of blood flow (perfusion) has clinical relevance in multiple fields 1 where it is useful to be able to When laser light illuminates a diffuse object, it produces a random interference effect known as a speckle pattern. If there is movement in the object, the speckles fluctuate in intensity. These fluctuations can provide information about the movement. Speckle imaging describes a range of high-resolution astronomical imaging techniques based on the analysis of large numbers of short exposures that freeze the variation of atmospheric turbulence. They can be divided into the shift-and-add (" image stacking ") method and the speckle interferometry methods. called speckle.

Optical clearing agents (OCAs) and many chemicals are widely used in functional diagnosis of skin tissues. Numerous studies are associated with the transcutaneous diffusion of OCA in epidermal, dermal, and hypodermal tissues, Laser Speckle Contrast Imaging Overview LSCI is a simple technique that requires only a camera with an appropriate lens, a low-power monochromatic (i.e. single-colour) laser, and a lens to expand the laser beam. speckle contrast analysis algorithm to enhance non-inv asive high resolution laser speckle functional imaging of cutaneous microcirculation,” Scientiﬁc Reports 7 , 41048 (2017). 2011-03-01 Laser speckle contrast imaging (LSCI) is a technique based on the dynamic change in this backscattered light as a result of interaction with red blood cells.

Unlike DOSI and SFDI which are aimed at diagnosing melanoma, the goal of LSI is more oriented towards evaluating the process of non-invasive melanoma treatments such as Photodynamic Therapy (PDT) . Laser speckle imaging is a diagnostic technique in which the features of scattered coherent light are explored.

The technique uses the phenomenon of laser speckle.
